Answer:

Step-by-step explanation:

Alright, lets get started.

When two secants intersects outside a circle then the measure of the angle formed is half of the positive difference of the measures of the intercepted arcs. (Please refer the diagram I have attached)

Hence the measure of ∠1 is :

∠1= $\frac{1}{2}(100-30)$

∠1= $\frac{1}{2}*70=35$

hence the answer is 35°. : Answer

Hope it will help :)

Students in a world geography class want to determine the distances between cities in Europe. The map gives all

galina1969 [7]

Using a proportional relationship, we have that:

a) The constant of proportionality is of 0.625, hence the equation is: $y = 0.625x$ .

b) The distance of two cities that are 5 miles apart is of 8 kilometers.

c) When they are 200 kilometers apart, we have that the distance in miles is of $y = 0.625(200) = 125$ .

<h3>What is a proportional relationship?</h3>

A <em>proportional relationship</em> is a function in which the <u>output variable is given by the input variable multiplied by a constant of proportionality</u>, that is:.

$y = kx$

In which k is the constant of proportionality.

Item a:

From the graph, when x = 8, y = 5, hence:

$y = kx$

$5 = 8k$

$k = \frac{5}{8}$

$k = 0.625$

The constant of proportionality is of 0.625, hence the equation is: $y = 0.625x$ .

Item b:

From the graph, when y = 5, x = 8, hence:

The distance of two cities that are 5 miles apart is of 8 kilometers.

Item c:

When they are 200 kilometers apart, we have that the distance in miles is of $y = 0.625(200) = 125$ .

What is 3x² + 3x - 36 and x² - 3x - 28 in factored form?

satela [25.4K]

Answer:

3x² + 3x - 36=

(3x+12)(x-3)

x² - 3x - 28=

(x+4)(x-7)

Step-by-step explanation:

For both equations use the method called the "Cross Method". It is useful for these type of factorisation questions called "Trinomials".

For more info on the cross method.

Joe can clear a lot in 2.5 hours. His partner can do the same job in 7.5 hours. How long will it take them working together?

irina [24]

Answer:

The time required by both persons to complete the work T = 1.458 hours

Step-by-step explanation:

Given data

Time required by Joe to clear a lot $T_1$ = 2.5 hours

Time required by his partner to clear a lot $T_2$ = 2.5 hours

Time required by both persons to complete the work by working together

$T = \frac{T_1 T_2}{T_1 + T_2}$

$T = \frac{(2.5)(3.5)}{2.5 + 3.5}$

T = 1.458 hours

Therefore the time required by both persons to complete the work T = 1.458 hours
